Hello kishore_reddy

Thank you very much for your help about setting up the CMS.

However, I try to add new feature to the CMS with new  model view controller and stuck with some following error

Server Error in '/' Application.

I tried to simplify webboard feature by output only message to see if it work integrated with the CMS. 

I am very appreciate if you could add new feature or module (ie. Task List) and describe it step by step. I think it must be

the great article for people who want to extend the CMS.

If it 's not convenient for you just let me know how to extend and which class do I need to implement and where register some class.


Thank you very much.

I'm writing up documentation on this codeplex site wiki for the cms.

I'll be uploading the docs today on the wiki first and also as a .html file that is part of the source code.

I've added documentation for Widgets and Modules in the Documentation tab. I'm continuing the documentation but this a start. Also take a look at the Configuration section.

As per your question on the classes to extend, I'm writing that up now in the Modules section. Should be done shortly.

Kishore, thank you very much.

Kishore, Thann you for your documentation.

It’ s useful, easy to follow and help me a lot to create my own module.

Actually, I created simple module for learning creating-custom module.
The module ‘s data table has only two field Id and Name to make it simple.

After crating model view controller for customer, I debugged program and point to


And the does not return customer name.

I tried to check if there is problem in repository class and wonder if I don’t have to override and put sql statement or LINQ to Entity to access database in public override Customer Get(int id) since the repository derives from RepositorySql<Customer>

The base class can do internally to get customer from id




 public override Customer Get(int id)


            Customer entity = base.Get(id);


            return entity;



I also attach source file and please could you check it out if I forgot or do something wrong.

Just click this link to download file.


Thank you very much for your kindness

Solved !!

I've added CommonLibrary.NET source to debug the CMS and found the problem with RowMapper.

I passed the wrong field name.


public partial class CustomerRowMapper : EntityRowMapper<Customer>, IEntityRowMapper<Customer>

        public override Customer MapRow(IDataReader reader, int rowNumber)
            Customer entity = _entityFactoryMethod == null ? Customer.New() : _entityFactoryMethod(reader);
            entity.Id = reader["Id"] == DBNull.Value ? 0 : (int)reader["Name"];
            entity.Name = reader["Name"] == DBNull.Value ? string.Empty : reader["Name"].ToString();

            return entity;



Anywhere, thank you very much for your contribute of great ASP.NET MVC CMS
